There is sometimes variable finish on the face of your mouldings. For example, last year I ordered several lengths of L1853 White Beech. There were several places where the beech laminate had been changed to another sheet, leaving "fingers" of join, which resulted in quite a lot of wastage of (for me) quite an expensive moulding. I suppose I could have rung up and I imagine I would have been invited to return the offending lengths. I would rather not have to wrap up several lengths and go through the rigmarole of returning them, I just had to make do as best as I could, with a bit of wastage. Otherwise I have no complaints, which is why we use Lion each year before our annual exhibition.
